Salts can be easily identified, since they usually consist of positive ions from a metal with negative ions from a non metal. The salt we put on our fries is actually sodium chloride and is made up of metal Na1+ and non metal Cl1- ions. Often you will see this written as Na+ and Cl- (the 1 is dropped) or simply NaCl.
Salt is a mineral composed of sodium and chlorine. Neither can exist alone in natural form. Together, they form the chemical compound that is sodium chloride. To geologists, salt is known as halite. Salt is a crystal of the isometric system, meaning it is usually cubic and perfectly symmetrical. Pure salt crystals are colorless, although a pile of them will appear to be white. Impurities in the crystals may cause salt to be various shades of yellow, red, blue or purple.
